The ProMag SMI26 is a 7-round steel magazine purpose-built for the Smith & Wesson M&P Shield in 9mm. If you run a Shield as a carry gun or range workhorse, you know the factory magazine capacity can feel limiting—especially during training sessions or when you want a spare loaded and ready. This aftermarket magazine closes that gap, giving you a practical capacity bump without changing platforms.
Built from heat-treated carbon steel with a black-oxide finish, the SMI26 resists corrosion and stands up to the wear of regular use and reholstering. Inside, a heat-treated chrome-silicon spring and injection-molded follower ensure reliable feeding and smooth operation. The magazine is engineered specifically for 9mm M&P Shield models, so fit and function are dialed in from the start.
Whether you're stocking spares for the range, building a backup loadout, or simply want more capacity on hand, this magazine pairs seamlessly with your Shield. Made in the USA, it's a no-nonsense upgrade that gives you more rounds downrange between magazine changes.
